content analysis | accurately weigh about 3.5g of sample, move into a flask, add 40.0ml of 1mol/L sodium hydroxide solution, and rinse the side wall of the flask with water. Cover the surface dish, boil over low heat for 1h, and titrate excess sodium hydroxide with 1mol/L sulfuric acid to Ph = 6.5 after cooling. At the same time, blank test is carried out and necessary correction is made. Per Mi,1mol/L sodium hydroxide is equivalent to 236.3mg (on a dry basis) of this product (C14H20O3). |
